What is considered the supreme law of the land?

The Constitution is regarded as the supreme law of the land because it establishes the foundational legal framework for the United States government and its relationship with the states and citizens. It outlines the structure of government, delineates the powers and responsibilities of various branches, and safeguards individual rights through amendments. The supremacy clause, found in Article VI, explicitly states that the Constitution and federal laws made in accordance with it shall take precedence over any state laws or constitutions. This principle ensures that all governmental actions and legislation are subordinate to the Constitution, providing a consistent and unified legal standard across the country. In this way, the Constitution serves as the highest authority in the American legal system.
